When I started at the client. I was told, that since, I am the only one performing my duties. There will be days that I work late or on the weekends, but I can accumulate that comp time. When I started taking the comp time. They complained that I am not in the office.
My account manager, instead of explaining that I am entitled to the time off, asked if I actually do a days work in the office. That maybe I didn't need to work off-hours and accumulate hours. Felt like victim blaming. Especially, since some work cannot be performed during work hours. So, if I work 5 hours in the office and 4 hours at home. That just brings up the same issue. I am also on 24/7 on call.
I've also seen 2 people who were told they were terminated late at night, when they were home.
One person was a rocket star. Almost everyone loved him. But 2 out 1000 people didn't like his attitude and that was enough for CapGemini to terminate him to make the client happy.
Good stepping stone if you want to get exposed to more careers.
Don't expect any loyalty or having them back you up. Customer's always first
