Over a third (36%) of employees in the UK start the week on Monday morning feeling tired despite the weekend break, with high levels of depression, stress and anxiety.
According to Canada Life Group Insurance, more than one in ten (12%) describe themselves as feeling depressed, while 20% are stressed or anxious.
An overall sense of financial security also aids workplace performance, 24% of those who have financial protection say knowing they are covered improves both their workplace motivation and productivity.
In contrast, 32% indicated a higher salary would boost their motivation.
Workplace motivation is most negatively affected by work related stress (16%), while 14% find that unpleasant colleagues damage their motivation at work.
The same proportion (14%) blame a lack of incentive such as recognition or bonuses, while 13% say an unmanageable workload makes it hard for them to feel motivated at work.
Paul Avis, Marketing Director at Canada Life Group comments: "Starting work feeling depressed, anxious, tired and stressed signals that employees are experiencing serious problems in the workplace but are neglecting to address them.
"If employees are really unhappy about tackling these problems head on, an Employee Assistance Programme can provide third-party assistance and advice.
"If employees' problems are money related, employers providing financial protection, such as group income protection, can go a long way to improve financial security and also contentment and productivity at work"
