I have set hours Monday to Friday, but if I need time off for an appointment or family matter, they are understanding and very flexible. They allow me to make up for lost time.
The hours are typical construction site, but there are some days of overtime and night shifts depending on the job and scpe of work. They allow for time off though for personal items.
I have set hours 8-5, but they are very flexible and understanding if there is an appointment I need to go to, or a family matter
