Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means change in form. The original rock (protolith) is subjected to heat (temperatures greater than 150 to 200 Â°C) and pressure (1500 bars), causing profound physical and/or chemical change.extures are separated into foliated and non-foliated categories. Foliated rock is a product of differential stress that deforms the rock in one plane, sometimes creating a plane of cleavage. For example, slate is a foliated metamorphic rock, originating from shale.
Thereâs no time limit for how long the period of consultation should be, but the minimum is: 1  20 to 99 redundancies-the consultation must start at least 30 days before any dismissals take effect. 2  100 or more redundancies-the consultation must start at least 45 days before any dismissals take effect.
If an employee gives a two weeks' notice upon resigning a job, and the employer does not want that employee to be on the premises, then the employer should simply continue the employee's salary for the two weeks remaining in the employee's employment (and have the employee work from home on call).any employees incorrectly believe that employers are required to give them two weeks' notice upon termination. This is simply not true. Other employees believe that employers must tell them the reason they are terminating the employee.
