You can't have it both ways - anybody's routinely worked overtime is someone else's job.

Where I work (country, not company) everyone is restricted to working 1760 hours per year, overtime can be worked but is generally frowned upon by the country's department of labour. Regarding overtime worked, it is compulsory for individual employers to offer overtime rates, which are highly taxed, or, they must offer you paid time off in lieu, which is taxed at the normal rate. Most people go for the latter.
