Provide the theme summaries for the following conversation: 

Mr. Benson: Let's start with your workload for tomorrow. 
Claudia: I have a couple of ongoing projects and 2 conference calls planned for tomorrow. Except for the latter, nothing too urgent that cannot be put off until later.
Andy: I have a huge deadline for tomorrow and really have to focus on it. Probably will finish by midday and from then on nothing too urgent.
Mark: I don't know how to tell you this, but I was supposed to have the next day off so I planned to finish all urgent tasks tomorrow.
Mr. Benson: Mark, can you cancel the day off? We really need your help here.
Mark: That's not really that important. I just need to make a few phone calls. When will you be back, Mr. Benson?
Mr. Benson: On Tuesday. Thank you, Mark. 
Mark: Can I have Wednesday or Thursday off then? 
Mr. Benson: Of course. I'll tell Lona later to book both days for you. One is on the company.
Mark: Thank you, sir. I'll be right back. 
Mr. Benson: All right. Claudia - Since you have the smallest workload I want you to call all out major clients and ask them about client satisfaction. Lona has the survey, so ask her for it. 
Claudia: Of course. 
Mr. Benson: You don't have much time, because I'll need the processed data by 11.
Claudia: You'll have it on your e-mail by 10:30.
Mark: I'm back.
Mr. Benson: Thank you, Claudia. Andy - I need you to prepare a presentation on our company. Something for laymen, not too complicated and not too specialised. A lot of positive figures.
Andy: No problem, sir. Do you need any specific data?
Mr. Benson: Financial, social and something intangible. 
Andy: By when do you need it?
Mr. Benson: By the end of the day. 
Andy: Will do. 
Mr. Benson: Thank you, Andy. Mark - you get the hardest task. I want you to do some data mining.
Mark: Data mining? What am I looking for?
Mr. Benson: I want you to pull everything you can find on our clients' financial situation before the agreement with us, one month after signing and their current standing. 
Mark: That's a lot of work. I don't know if that's doable in one day. 
Mr. Benson: I'm sure you can manage. 
Mark: And when do you need it?
Mr. Benson: Like Andy's presentation - by the end of the day.
Mr. Benson: Since everyone knows what to do, let's make it work!

Mark will cancel his day off on Mr. Benson's request. Claudia will call out major clients to ask about their satisfaction and provide data by 10:30. Andy will prepare a presentation on the company byt the end of the day. Mark will do data mining on client's financial situation.
