sky9,
I feel that it may fall on deaf ears. The current opinion of employers seem to be that casual sickness is on the rise and is becoming a problem. A major UK supermarket chain recently introduced a policy of deducting wages for sickness (endorsed by the union as well!). And I heard today that York council are introducing a policy wereby employees have to call a nurse when they report sick, on the basis that they can receive expert medical assistance for their ailments. Some would argue that a nurse is more qualified to judge whether someone is swinging the lead than a manager would be! As long as this opinion pervades, their will be an element of suspicion about anybody reporting sick for duty.
