It is certainly true that it had been stated in the contract that when one doesn't meet the standards, he/she has to leave the company.
However, even before the first person was kicked out, it was already determinded by the management that a certain amount of newbies had to leave. Logically, they took out some troublemakers first and perhaps some persons who -for whatever reasons- were 'underachieving'. Remember, all 30 persons had their employment contracts before starting training.
That having said, my greatest concern is that Pegasus management told/write the group that linetraining would take an x amount of time but in reality it took much, much longer. Resulting in monetary problems with a lot of the guys and most of all, loss of income for everyone. Imagine that your montly income would be around €2500,- and that your linetraining would take 4 months extra; that means a loss of income of €10.000,- Some guys grouped together and others wrote on their individual behalf a letter to PGS management to inquire about the duration of the linetraining. Pegasus systematically denied that there have been any promises or gentlemens agreement in the past regarding the duration of linetraining. For me this fact had been a serious breach of mutual thrust...But anyway, some nationalities where receiving funds from their homecountry so it didn't hurt that much.
Another issue that was not appreciated by a small group is that Pegasus changed the employment contracts. The interesting part was a salary increase but this only would take effect after the initial employment contract while the 'notice period' to leave the company was increased from 1 to 3 months. Now tell me, does this make sense? It is a well known fact that only a handfull of people are allowed to stay after the initial contract which ends at the 31st of october this year.
